ive just upped the boost on 91 auto and every time i accelerate or over take it drops down and the tail end keeps spining out, i have a few mods (decat down pipes, mongoos system,hks filter,impul high power ecu and boost upped to 14psi).

i have 255 conental sport contact 2 tyres on 17s and standard shocks and elbich springs. i hear a better suspension set up can give you more traction?

any ideas? its a bit dangerous:lol:

rain? :D

in the dry!

in the dry!

slow down:tongue::D

:lol::lol::lol:

:biggrin: i would but when im in the z all other cars seem like there traveling so slowley:innocent:

suspension could be to hard, dampers not do the job. I think your right in saying it needs setting up.

how have you upped the boost?

Just one question......

 

......how's the tread on the tyres? Conti Sport Contact tyres are normally pretty good - I have Sport Contact 3s (MO fitment) all round on my SLK350 and I don't usually have a problem with grip......

 

....until the rears get to around 3mm!! It can be a bit slippy then but the TC kicks in too early:blushing:

 

I have the new Goodyear Eagle F1 Asymetrics all round on my ZX and there's no grip issues whatsoever come rain or shine. Or even moderaterly icy roads!!

 

Richard:balloon:

also, how old are the tyres, they could have gone off / hard

put some concrete blocks in the boot & let the tyre pressure down!! lol sorry that was no help whatsoever i'll get my coat!!!:blushing:

Get some better tyres that's the first step I'd say.

tyres are prob geting down to about 4.5mm and are quite old + dont get used a lot so could well be that, il have a look on the tyre thred a see what every 1 recomends. boost upped with an ebc i have a guage to make sure its not over boosting.

 

i would but it ways so much allready:yes:

it far more likely to be an alignment/worn bush issue. replacing any worn bushes and having a propper alignment will transform the car.

 

you say the car is lowered so as a start the car will be out of alignment even if it was perfect before. The rear suspension on these cars is very complex and has lots of bushes and tends to need setting up quite often

I would say that if this is happening in the cold wet or icy weather then this is perfectly normal! Kicking down a gear or 2 at 350bhp ish will have rear stepping out!
